Provided are a display apparatus and an operation method thereof for preventing image flicker when displaying mixed images: generating a first image corresponding to video content on a first plane, generating, on a second plane, a second image, outputting a mixed image that is a mixture of the first image and the second image, generating a third image on a third plane corresponding to the mixed image, and displaying the third image based on removal of the first image from the display.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
3. The display apparatus of claim 2, wherein the processor is further configured to execute the at least one instruction to, generate the third image by copying the mixed image on the third plane.
5. The display apparatus of claim 2, wherein a third display priority of the third plane is lower than a first display priority of the first plane and higher than a second display priority of the second plane.
8. The display apparatus of claim 2, wherein the second image is superimposed over the first image in the mixed image.
11. The display apparatus of claim 10, wherein the video module is further configured to generate the first image by scaling and correcting the first image on the first plane.
12. The display apparatus of claim 10, wherein the graphics module is further configured to generate the second image by scaling and correcting the second image on the second plane.
13. The display apparatus of claim 10, wherein the video module supports a resolution higher than a resolution of the graphics module.
16. The method of claim 15, wherein the generating of the third image comprises copying the mixed image on the third plane.
18. The method of claim 15, wherein a third display priority of the third plane is lower than a first display priority of the first plane and higher than a second display priority of the second plane.
This invention relates to a system for managing multiple display planes in a graphical user interface, addressing the challenge of efficiently organizing and prioritizing visual content in layered displays. The system includes at least three display planes, each assigned a distinct priority level to control their rendering order. The first plane has the highest display priority, ensuring it appears above all others, while the second plane has the lowest priority, rendering beneath the others. The third plane is positioned between the first and second planes, with a priority higher than the second plane but lower than the first. This hierarchical arrangement allows for flexible content management, enabling dynamic adjustments to the visibility and stacking order of graphical elements. The system may also include mechanisms to modify these priorities in real-time, such as user inputs or automated triggers, to adapt the display configuration based on context or user preferences. The invention is particularly useful in applications requiring layered interfaces, such as augmented reality, gaming, or multi-window operating systems, where precise control over visual hierarchy is essential for usability and performance.
